WSDL 客户端调用失败

Question

第一次使用 SOAP 服务。我需要调用这个网络服务。 http://demomt.weblite.com.my/TS_Services/SubmissionsService.asmx?WSDL

这是我使用 wsimport

生成的 11 个存根中的 2 个

我试了一整天，但我不断收到此错误消息。为什么？我怀疑是因为我没有正确通过身份验证 header。但与此同时，我想知道生成的存根为什么不附带 Authentication header 作为方法参数？那是正常的吗？需要帮忙。我很困惑。

Exception in thread "main" com.sun.xml.internal.ws.fault.ServerSOAPFaultException: Client received SOAP Fault from server: Server was unable to process request. ---> Object reference not set to an instance of an object. Please see the server log to find more detail regarding exact cause of the failure.

我试过了运行TestApplication

public class TestApplication {

    public static void main(String[] args) throws MalformedURLException {
        MailAdapterApplication adapterApplication = new MailAdapterApplication();
        adapterApplication.run();
    }

    public void run() throws MalformedURLException {

    WebLITETSServices services = new WebLITETSServices();
    WebLITETSServicesSoap servicesSoap = services.getPort(WebLITETSServicesSoap.class);
    Map<String, Object> req_ctx =((BindingProvider)servicesSoap).getRequestContext();
    Map<String, List<String>> headers = new HashMap<>();
    headers.put("Username",Collections.singletonList("sansun@weblite.com.my"));
    headers.put("Password", Collections.singletonList("P@ssW0rd32!"));
    headers.put("APIKey", Collections.singletonList("QdrLKxog"));

    req_ctx.put(MessageContext.HTTP_REQUEST_HEADERS, headers);
    System.out.println(servicesSoap.getTemplateList());

    }

}

Answer 1

Client received SOAP Fault from server: Server was unable to process request.
Object reference not set to an instance of an object.
I keep getting this error message. Why?

确实您确实调用了该服务，但是服务器 returned 了一个带有错误消息的错误代码，其中 returned 有效负载没有映射到任何预期的 return 类型或肥皂故障异常。您提供的文本中没有更多信息。

检查真正 returned 的响应状态代码和负载将非常有用。如何记录respone payload取决于你使用的webservice库(cxf, axis2, ??)

I suspect because i did not pass in the authentication header correctly.

你应该确认怀疑，从提供的信息中无法分辨。不过，如果您没有提供任何身份验证信息，则很有可能

But at the same time i'm wondering how come the generated stub does not comes with Authentication header as a method param? is that normal? Need help. I'm so confusing.

我假设在 "Authentication header" 下你指的是 AuthHeader header。您可能需要在调用 wsimport 时启用 header 生成，这取决于所使用的框架。从默认 JDK 使用 wsimport 时，尝试使用 -XadditionalHeaders 参数
